Outdoor Temperature Alarms

A high and low outdoor temperature alarm may be set on the forecast station.
Note: When multiple sensors are connected on different channels, a high and/or low
temperature alarms may be set for each channel.
Set Temperature Alarm Channel 1
1. Press and release the CH button to select channel 1 (when multiple sensors in use).
2. Hold the TEMP ALERT button until the High Temp Alert icon appears and the temperature will
flash. Use the + or - button to select your High Temp alarm value. Press and release the SET
button to move to the Low Temp alarm.
3. The Low Temp Alert icon will appear and the temperature will flash. Use the + or - button to select
your Low Temp alarm value. Press and release the SET button to confirm and exit to current
temperature.
4. The Temp Alert icon will show in the outdoor temperature area when a temperature alarm is active. When
the temperature alarm sounds, the Temp Alert icon and the temperature value will flash. Press any button to
silence the alarm temporarily.
Set Temperature Alarm Channel 2 & 3

Use the CH button to select the channel. Follow steps 2-4 above to set temperature alarms on other
channels.

DEACTIVATE TEMPERATURE ALARM: Press and release the TEMP ALERT button 3 times to deactivate
all temperature alarms. The alert icons will disappear.
Temperature/Humidity Trend Indicators (arrows)
The temperature (2°F/1°C) and humidity (3% RH) trend indicators update every 30 minutes or less.
 Temperature has risen in the past 3 hours.
 Humidity has risen in the past 3 hours.
 Temperature has not changed in the past 3 hours.
 Humidity has not changed in the past 3 hours.
 Temperature has fallen in the past 3 hours.
 Humidity has fallen in the past 3 hours.

Pressure Readings

Absolute Barometric Pressure Number

Barometric pressure is read by the forecast station. The numeric pressure value adjusts automatically as the
forecast station reads changes in air pressure. Since this number is absolute pressure, it may not be the same
as a local reporting station that reads in relative pressure.
Note: The number cannot be calibrated.

Absolute Pressure is measured in a vacuum without the influences of terrain, weather, water, foliage and
elevation. The air pressure it would be consistent at every elevation and decrease as it went higher.

Relative Pressure is a combination of air pressure and altitude. Relative air pressure will make readings in
local areas relative to each other to allow for proper forecasting.
